Does God exist?

Welcome to the debate arena! Today's topic: "Does God exist?". Your opponent's style: Devil's Advocate

God doesnt exist, I dont agree with the argument : "All contingent things require an efficient cause." This is empirically shakier than it sounds. Radioactive decay, vacuum fluctuations, and (on several mainstream interpretations of quantum mechanics) the collapse of the wavefunction are standardly treated by physicists as uncaused at the fundamental level — not "caused by something we haven't found yet," but genuinely without a determining efficient cause. A given atom of uranium-238 decays at an unpredictable moment with no prior physical event selecting that moment. The document's own Objection 5 concedes this is "a real distinction" and that some interpretations "really do posit brute, uncaused events at the fundamental level" — but then hides that concession in a subordinate clause. It shouldn't be hidden. If even one class of contingent physical events lacks an efficient cause, Premise 1 is falsified as a universal claim, not just weakened. The theist can retreat to "well, it has some cause even if not an efficient one" — but that's special pleading: redefining "cause" after the evidence contradicts the original claim.

You're smuggling necessity into contingency. Quantum indeterminacy doesn't prove uranium decay is uncaused—it proves we can't *predict* the cause. Unpredictability ≠ no cause. A radioactive nucleus at T1 differs physically from T2; something about that difference triggers decay. Call it "brute" if you want, but that's just relabeling ignorance, not solving it. Your real move is redefining causation to mean only "deterministic prediction." Why should the cosmological argument care? Even if some events lack *efficient* causes, contingent things still need *some* explanation for existing rather than not. Quantum mechanics explains the *how*, not the *why anything at all*. What explains contingency itself?
